@nprofile…r0kn "Too Tough" and "Buffoon." I can see how he would easily mix those terms up.

@nprofile…5lc3 I don't think ransomware is an allegiance thing. It is a money thing. So long as people in the US are wealthier and still willing to pay, the US will always be a target.
It's a hard sell to suggest the Russian government doesn't soak every last ruble out of its people.

@nprofile…fv4z Same when Trump says Canadians like the idea of being 51st state. We totally don't. We despise your government interfering with ours, and your propaganda appearing on billboards here. All hell will break loose if there is an attempt.
If you hear someone suggest it, remind them this is how you'll go from being the greatest ally to the greatest enemy in a single step.

@nprofile…r0kn Haha that would be awesome if you end up rich over the next few years of just playing ping pong with a single stock.
There really isn't much incentive to diversify if you're only holding for a few hours or days at a time.

@nprofile…r0kn Smart. There's some obvious excitement today. Hopefully the buzz doesn't wear off by Monday.
Do you have the equivalent of a Tax Free Savings Account like we have up here in Canuckville? I have, and use it for the obvious enough reasons. But (thankfully) I read an article that if I buy/sell too quickly, they assume I'm a day trader, and immediately classify it as income.
I'm prone to day trading, so now I'm super cautious with that appearance.

@nprofile…r0kn Nice indeed. All in a day's work, as they say in the biz. Judging by how it bounces all over the place like a day trader's wet dream, I assume you have already sold as well.

Okay this made me read the rest of the article. :ablobcatrainbow:
It's two religious factions arguing about why the other should go away. So the intro was pretty much on point.
Speed only barely matters on modern computers. Yes you can make stupidly slow code, but that's if you suck, and don't notice how your code is dragging everything down. (Sorry, did Oracle just call?)
I met a guy who programmed for Thomas The Tank Engine (the little kiddie's thing). He's a Lisper. But his Lispy language of choice spits out Java, so here we are again.
It's not possible to win a war like this.
It is a confusing article, because I think its conclusion is way up where the paragraph starts with "What I want by coming from small ..." but I really can't tell.
I get what the subject is. Kinda. I barely get the conclusion because it is so fudged.

@nprofile…l9v9 @nprofile…sr67 @nprofile…re6y Religion sucks. I didn't read the entire article because the intro makes it so obvious that it is religious.
Languages constantly absorb Lisp features because it was obviously the right way to go. People wanted ~simple~ slobberproof instead. Yet, they never got there.
Lisp got simpler, but by that time we had sofa king many toy languages that eventually became real languages, that there is no way to back track.
So here we are. Lisp is ancient. It is incredibly powerful (and the only reason I retain my interest in it since also the 80's), but the battles are useless.
Wait until we find the fuzzy line between quantum computing and AI, and then nobody ever has to code... just have to say what you want, burn down a rainforest, and wait for the product.
The religious part has been going on so long you'd think people would just tire of it and stop repeating it. But noooo, can't be done, I guess.
I'm going to post a much nicer article later this week about using #commonlisp to interpret scientific notation.
I don't care about whether it can be done in other languages. In fact, it would be really weird if it couldn't be.
I celebrate the differences, so hopefully the article I'm writing (it's done... just making it more readable) will be entertaining enough that people who traditionally involve themselves in these silly battles will just put forth code and enjoy the fact that it works, and is sometimes really clever.

@nprofile…de2h Out of curiosity, how massive is the executable file?
Just curious, because I assume the java doesn't embed the entire interpreter like Common Lisp binaries would.

@nprofile…skc4 @nprofile…kjrn One thing I do every New Years, is read the year before's predictions for the year that just passed. So this New Years, I looked at the predictions for 2024.
What I've learned from this, is that Psychic Nikki and absolutely every other one just make shit up as they go, and then re-publish the ones they got right.
Exactly as you said.
But their correct predictions are very low percentages. They aren't psychics. They just say whatever they want, and oddly get a paycheck for it.

@nprofile…kzuj @nprofile…l9v9 Hah, this reminds me of this craziness from my early days:
First is first, last is a list of last.
When given the list ((10 (20 30 40) 50) 60 70)), output the first of the last of the first of the last of the first element, and name the accessor.
(The answer is 30, and CADADAR, but of course you all already knew that right away)

Last night I tried to teach ChatGPT how to do the Akinanator quiz.
It is pretty good when it is asking questions, although sometimes you have to remind it to avoid just listing off random names.
However when it is your turn to ask questions, you get a definite feeling that it doesn't come up with a person or thing until after you start asking your questions.
You can ask some outrageously specific questions, and surprisingly hit. You can guess what it is "thinking" wildly quickly lol.
So it's sorta pretending to play, but makes you look like a wizard!

@nprofile…5k2y Technically, this isn't a political issue you're bringing up. It's a straight up security breach accomplished in front of everyone's eyes, and far too many people being just fine with it.
The fact that it's in the political arena doesn't change that aspect.

@nprofile…5k2y This reminds me of my early days working in a bank's InfoSec dept. Their risk model, called ECHO ETUN, had the T for the technical skill required for someone to exploit the vulnerability.
They got pissed every time I pointed out the difference between the lowest rating and highest rating was a PERL script uploaded to a newsgroup.
But I wasn't wrong. Just inconvenient for a security group that reports directly to the CTO - the very person who prioritizes the developers that coded it that way to begin with.

Guitar players of Mastodon, what do you think of my guitar playing 14 years ago. I'm thinking about making a series on how to play these kinds of riffs. Fast, but definitely not Yngwie style.
Yes, that street name really is my name, and it exists. (Just saying that, 'cos of the weird replies I got on this 14 years ago)

What I'm most impressed with re: the #eclipse is just how small of a sliver of sun is needed to light everything back up like it's 8 in the morning again.
That sliver of sun is bright like an arc welder. But more so.

Why doesn't #Python have #Lisp style macros?
For example, here is something that should be able to be used in code generation:
s = "This is a string that I want to turn into a list"
print(s.split(' ', -1))
It's a lame example, but it shows the point cleanly. With a Lisp style macro, I would be able to compile this as a list, instead of creating the lisp at runtime every time.
There doesn't really seem to be anything stopping Python from being able to do this, except the lack of implementation.
Or is it there, and I just don't know about it yet?
Maybe a related question: Does Python have something like Lisp's (compile ....) because that would immediately call for Lisp style macros!
